7y - 3x = -5
-3x = -7y - 5
x = 7/3y + 5/3
The two different ways of finding the area are,
Case 1 = assume horizontal rectangles,
Case 2 = assume vertical rectangles.
<h3>What is a rectangle?</h3>
the rectangle is a four-sided polygon whose opposites sides are equal and has an angle of 90° between its sides.
Here,
case 1,
As shown in the image
Area = sum of horizontal rectangles
Area = 10 * 3 + 2 * 5 + 2 * 1
Area = 30 + 10 + 2
Area = 42
Case II,
As shown in right figure,
Area of the vertical rectangles
Area = 3 * 5 + 5 * 3 + 2 * 6
Area = 15 + 15 + 12
Area = 42
Here, the area in case 1 is equal to case 2.
Thus, the two different ways of finding the area have shown above.

#SPJ1
2hr = 2km
1hr = 2km ÷ 2hr
= 1km
So, Tom's average speed is 1km/hr
Answer:
-1/2
Step-by-step explanation:
we know x=9
putting the value, we get,
-5/6(9) + 7
-15/2 + 7
-7.5 + 7
= -0.5
= -1/2
False because 4x-3(5x-1) is -14x and 3+9x is 6x
